Now, it’s not exactly Earthlike . . .

[_The Telegraph_](http://www.dailytelegraph.com.au/news/breaking-news/us-discovers-new-waterworld-planet-gj1214b/story-e6freuyi-1226277938834) reports:

> [@](#):
>
> Researchers at the Harvard-Smithsonian Centre for Astrophysics said they have identified an entirely new kind of planet, dominated not by rock, gas or other common materials, but water.
> 
> The planet is “a waterworld enshrouded by a thick, steamy atmosphere”, they said in a statement, after scrutinising the planet with NASA’s Hubble Space Telescope.
> 
> “GJ1214b is like no planet we know of,” astronomer Zachary Berta said. “A huge fraction of its mass is made up of water.”
> 
> GJ1214b was discovered in 2009 by the ground-based MEarth Project. Described as a “super-Earth”, it is about 2.7 times Earth’s diameter and weighs almost seven times as much.
> 
> Further studies in 2010 led to scientists suspecting that the planet, where the temperature is some 232 Celsius, was largely covered in water. This was confirmed by Mr Berta and his co-authors using Hubble to study the planet when it crossed in front of its host star.

Still . . . if there’s water . . . If we assume water is essential to life . . . What life-forms could live in hot water under high gravity? Anybody better at xenobiology than I care to speculate? 🙂

Panned I know… but imo the movie was somewhat brilliant science fiction.

Probably critters similar to what lives near to deep sea vents on Earth. If the world-ocean is hugely deep however then it may be largely sterile since there will be little source of nutrients for anything near the surface. If the seabed is a hundred or a thousand miles down and there’s no land to erode minerals into the ocean, all the minerals needed for life will be far away from the sunlight at the surface.

Gizmodo managed to completely mangle the science on this, saying that “most” of the planet was water, when the original article only claimed “significantly more than Earth” (which is at 0.02% water).

What would happen to a planet that was actually 50%+ water? Would the oxygen and hydrogen combust once subjected to a planet’s worth of gravity?

If the temp is 232 °C, wouldn’t it be Steamworld, not Waterworld? Or is the gravity sufficient to keep the water liquid at that temp?

Not only that, apparently the gravity is sufficient to produce something called “hot ice.”

I would imagine the sea life would be similar to what exists at the bottom of the sea and/or around hydrothermal vents, where a large variety of creatures exist under extremely high pressures and heat, conditions under which life would seemingly be impossible.

No. Water is hydrogen “ash” already.

If “planet’s worth” was enough mass, it would create nuclear fusion (like any large mass). Otherwise I suppose it would be more like a gas giant like Uranus or Neptune.

You could hard-boil a heck of a lot of eggs on GJ1214b.

Well… it depends. They’d probably start out as extremophiles, sure. But after 1 million years? 100 million years? 1 billion years? The real answer is that we really don’t know. We’re in a puddle that happened to conform to the hole that it was poured into, we have no idea what shape other puddles will be in, and we won’t know much until xenobiology is an actual science rather than a WAG’ing game.

_sigh_ Well, I guess we’ll just have to go and find out. Invent an FTL drive, somebody.

Sorry, I built one in the garage, but the Test Pilot I selected has been away from the board for a while.

At those temperatures and pressures, water on[GJ 1214 b](http://en.wikipedia.org/wiki/GJ_1214_b) can be lots of cool stuff:

> Because of the varying pressure at depth, models of a water world include “steam, liquid, superfluid, high-pressure ices, and plasma phases” of water. Some of the solid-phase water could be in the form of ice VII.
